CAUTION

The level may even lead to a serious consequence according to conditions. Both instruction levels must be followed because these are important to personal safety.

Incorrect handling may caus e hazardous conditions, resulting in death or severe injury.

Incorrect handling may caus e hazardous conditions, resulting in medium or slight injury, or may cause only material damage.

1. Electric Shock Prevention

WARNING

While power is ON or when the drive unit is running, do not

open the front cover. Otherwise you may get an electric shock.

z Do not run the drive unit with the front cover or wiring cover

removed. Otherwise you may access the exposed highvoltage terminals or the charging part of the circuitry and get an electric shock.

z Even if power is OFF, do not remove the front cover except

for wiring or periodic inspection. You may accidentally touch the charged drive unit circuits and get an electric shock.

z Before wiring or inspection, power must be switched OFF.

To confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involve d in wiring or inspection shall wait for at least 10 minutes after the power supply has been switched OFF and check that there are no residual voltage using a tester or the like. The capacitor is charged with h igh voltage for some time a fter power OFF, and it is dangerous.

z This drive unit must be earthed (grounded). Earthing

(grounding) must conform to the requirements of national and local safety regulatio ns and electrical code (NEC section 250, IEC 536 cl ass 1 and other appl icable standards).

z Any person who is involved in wiring or inspection of this

equipment shall be f ully competent to do the work.

z The drive unit must be installed before wiring. Otherwise

you may get an elect ric shock or be injured .

z Setting dial and key operations must be performed with dry

hands to prevent an ele ctric shock. Otherwise yo u may get an electric shock. Do not subject the cables to scratches, excessive stress, heavy

loads or pinching. Otherwise you may get an electric shock.

z Do not change the cooling fan while power is ON. It is

dangerous to change the cooling fan while power is ON.

z Do not touch the printed circuit bo ard or handle t he cables

with wet hands. Otherwise you may get an electric shock.

z When measuring the main ci rcuit capacitor capacity, the DC

voltage is applied to the motor for 1s at p owering OFF. Never touch the motor terminal, etc. right after powering OFF to prevent an electric shock.

PM motor is a synchronous motor with embedded

z A

magnets. High-voltage is generated at motor terminals while the motor is running even after the drive unit power is turned OFF. Before wiring or inspection, the motor must be confirmed to be stopped. For applications where the motor is driven by the load, the low-voltage manual contactor, which is installed at the drive unit's output side, must be opened before wiring or inspection. Otherwise you may get an electric shock.

2. Fire Prevention

z Drive unit must be installed on a nonflammable wall without

holes (so that nobody touches the drive unit heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.

z If the drive unit has become faulty, the drive unit power must

be switched OFF. A continuous flow of large current could cause a fire.

When using a brake resistor, a sequence that will turn OFF power when a fault signal is output must be configured. Otherwise the brake resistor may overheat due to damage of the brake transistor and possibly cause a fire.

z Do not connect a resistor directly to the DC terminals P/+

and N/-. Doing so could cause a fire.

CAUTION

3.Injury Prevention

z The voltage applied to each terminal must be the ones

specified in the Instruction Manual. Otherwise burst, damage, etc. may occu r.

z The cables must be connected to the co rrect terminals.

Otherwise burst, damage, etc. may occur.

z Polarity must be correct. Otherwise burst, damage, etc. may

occur.

z While power is ON or for some time after power-OFF, do not

touch the drive un it since the drive un it will be extremel y hot. Doing so can cause burns.

CAUTION

4. Additional Instructio ns

Also the following points must be noted to prevent an a ccidental failure, injury, electric shock, etc.

(2) Wiring

z Do not install a power factor cor rection capacitor or surg e

suppressor/capacitor type filter on the drive unit output side. These devices on the drive unit output side may be overheated or burn out.

z The connection orientation of the output cables U, V, W to

the motor affects the rotation direction of the motor.

z PM motor terminals (U, V, W) hold high-voltage while the PM

motor is running even after the power is turned OFF. Before wiring, the PM motor must be confirmed to be stopped. Otherwise you may g et an electric shock.

z Never connect a PM motor to the commercial power supply.

Applying the commercial power supply to input terminals (U, V, W) of a PM motor will burn the PM motor. The PM motor must be connected with the o utput terminals (U, V, W) of the drive unit.

CAUTION

(3) Trial run

z Before starting operation, each parameter must be

confirmed and adjust ed. A failure to do so may ca use some machines to make unexpected motions .

CAUTION

(4) Usage

WARNING

z A PM motor and the drive unit m ust be used in the specified

capacity combination.

z Do not use multiple PM motors with one drive unit. z Any person must stay away from the equipment when the

retry function is set as it will restart suddenly after trip.

Since pressing key may not stop output depending on

the function setting status, separate circuit and switch that make an eme rgency stop ( power OFF, mechanica l brake operation for emergency stop, etc.) must be provided.

z OFF status of the start signal must be confirmed before

resetting the drive unit fault. Resetting drive unit alarm with the start signal ON restarts the motor suddenly.

z Do not use a PM motor in an applicati on where a motor is

driven by its load an d runs at a speed higher than the maximum motor speed.

z Do not use a synchronized, induction, or induced-

synchronized motor, that is not a dedicated PM motor.

z Do not use the drive unit for a load other than the dedicated

PM motor. Connection of any other electrical equipment to the drive unit output may damage the equipment.

z Do not modify the equipment. z

Do not perform parts removal which is not instructed in this manual. Doi ng so may lea d to fault o r damage of the product .

z The electronic thermal relay function does not guarantee

protection of the motor from overheating. It is recommended to install an external thermal for overheat protection.

z Do not use a magnetic contactor on the drive unit input for

frequent starting/stopping of the drive unit. Otherwise, the life of the drive unit dec reases.

z The effect of electromagnetic interference must be reduced

by using an EMC filter or by other means. Otherwise nearby electronic equipment may be affected.

z Appropriate measures must be taken to s uppress

harmonics. Otherwise power supply harmonics from the drive unit may he at/damage the powe r factor correct ion capacitor and generator. When parameter clear or all parameter clear is performed, the

required parameters must be set again before starting operations becaus e all param eters re turn to th e initia l value.

z The drive unit can be easily set for high- speed operation.

Before changing its setting, the performances of the motor and machine must be fully examined.

z Stop status cannot be hold by the drive unit's brake

function. In addition to the drive unit's brake function, a holding device must be installed to ensure safety.

z Before running a drive unit which had been stored for a long

period, inspection and test operation must be performed.

z Static electricity in your body must be discharged b efore

you touch the product. Otherwise the product may be damaged.

z In the system with a PM motor, the drive unit pow er must be

turned ON before closing the contacts of the contactor at the output side.

z If you are installing the dr ive unit to drive a thr ee-phase

device while you are contracted for lighting and power service, consult your ele ctric power supplier.

CAUTION

(5) Emergency stop

CAUTION

z A safety backup such as an emergency brake must be

provided to prevent hazardous condition to the machine and equipment in case of dr ive unit failure.

z When the breaker on the drive unit input side trips, the

wiring must be checked for fault (short circuit), and internal parts of the drive unit for a damage, etc. The cause of the trip must be identified and re moved before turn ing ON the power of the breaker.

z When any protective function is activated, appropriate

corrective action mu st be taken, and the dr ive unit must be reset before resuming operation.

(6) Maintenance, inspection and parts replacement

NOTE

y The life of the drive unit is influenced by surrounding air temperature. The surrounding air temperature should be as

low as possible with in the permissible range. This must be noted especially w hen the drive unit i s installed in an

enclosure. ( Refer to Chapter1 of the Instruction Manual(Applied))

y Wrong wiring might lead to damage of the drive unit. The control signal lines must be kept fully away from the main

circuit to protect them f rom noise. (Refer to page 8)

y Do not install a power factor correction capacitor, surge suppressor or EMC filter (capacitor) on the drive unit output

side. This will cause the drive unit to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are connected, immediate ly remove them.

y Electromagnetic wave interference

The input/output (main circuit) of the drive unit includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the drive unit. In this case, ins tall the FR-BIF optional EMC filter (capacitor) (for use in the input side only) or FR-BSF01 or FR-BLF EMC filter (ferrite core) to minimize interference. ( Refer to Chapter 3 of the Instruction Manual (Applied)).

y Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices. y A PM motor cannot be driven by the commercial power supply. y A PM motor is a m agnet motor. High-voltage is generated at moto r terminals while t he motor is runni ng even after the

drive unit power is turned O FF. Before closing the contactor at the output side, make sure th at the drive unit power is ON and the motor is stopped.

Common terminal for contact input terminal (sink logic) and terminal FM.

Connect this terminal to the power supply common terminal of a transistor output (open collector output) device, such as a programmable controller, in the source logic to avoid malfunction by undesirable current.

Common output terminal for 24VDC 0.1A power supply (PC terminal). Isolated fr om terminals 5 an d SE.

Connect this terminal to the power supply common terminal of a transistor output (open collector output) device, such as a programmable controller, in the sink logic to avoid malfunction by undesirable current.

Common terminal for contact input terminal (source logic).

Can be used as 24VDC 0.1A power supply.

Used as power supply when connecting potentiometer for speed setting (speed setting) from outside of the drive unit.

Inputting 0 to 5VDC (or 0 to 10V) provides the maximum rotation speed at 5V (10V) and makes input and output proportional. Use Pr. 73 to switch between in put 0 to 5VDC input (initial setting) and 0 to 10VDC.

Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the maximum rotation speed at 20mA and makes input and output proportional. This input signal is valid only when the AU signal is ON (terminal 2 input is invalid). To use terminal 4 (initial setting is current input), set "4" in any of Pr.178 to Pr.182 (input terminal function selection) to assign the function, and turn ON AU signal. Use Pr. 267 to switch among input 4 to 20mA (initial setting), 0 to 5VDC and 0 to 10VDC. Set the voltage/current input switch in the "V" posit ion to select v oltage input (0 to 5V/0 to 10V).

1 changeover contact output indicates that the drive unit’s protective function has activated and the output stopped. Fault: discontinuity across B-C (continuity across A-C), Normal: continuity across B-C (discontinuity across A-C)

Switched Low when the drive unit rotation speed is equal to or higher than the 1r/min. Switched High during stop or DC injection brake operation. (Low is when the op en collector output tra nsistor is ON (conducts). High is when the tr ansistor i s OFF (does not condu ct).)

Common terminal of terminal RUN.

Used to output a selected monitored item (such as Rotation speed) among several monitored items. (Not output during drive unit reset.) The output signal is proportional to the magnitude of the corresponding monitored item.

NOTE

y To change the input specification for terminal 4, set Pr. 267 and the voltage/current input switch correctly, then input

the analog signal relevant to the setting. Applying a voltage with voltage/current input switch in "I" position (current input is selected) or a current with switch in "V" position (voltage input is selected) could cause component damage to the drive unit or analog circuit of output devices.

y Connecting the power supply to the drive unit output terminals (U, V, W) will damage the drive unit. Do not perform

such wiring.

(1) Cable size and other specifications of the main circuit terminals and the earthing terminal

Select the recommended cable size to ensure that a voltage drop will be 2% or less. If the wiring distance is long between the drive unit and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low speed. The following table indicates a selection example for the wiring length of 20m.

NOTE

Tighten the terminal screw to the specified torque. A screw that has been tightened too loosely can cause a short circuit or malfunction. A screw that has been tightened too tightly can cause a short circuit or malfunction due to the unit breakage.

y Use crimping terminals with insulation sleeve to wire the power supply and motor.

The line voltage drop can be calculated by the following formula:

Line voltage drop [V]=

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque reduction) in the low speed range.

(2) Total wiring length

Connect a PM motor within the total wiring length of 30m. Use one dedicated PM motor for one drive unit. Multiple PM motors cannot be connected to a drive unit.

NOTE

y Especially for long-distance wiring, the drive unit may be affected by a charging current caused by the stray

capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit function, or stall prevention function or a malfunction or fault of the equipment connected on the drive unit output side. If malfunction of fast-response current limit function occurs, disable this function. If malfunction of stall

prevention function occurs, in crease the stall level. ( Refer to Pr. 22 Stall prevention operation level and Pr. 156 Stall

prevention operation selection in Chapter 4 of the Instruction Manual (Applied))

(2) Wiring method

zWiring

Use a blade terminal and a wire with a sheath stripped off for the control circuit wiring. For a single wire, strip off the sheath of the wire and apply directly. Insert the blade terminal or the single wire into a socket of the terminal.

1) Strip off the sheath about the length below. If the length of the sheath peeled is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off. Wire the stripped wire after twisting it to prevent it from becoming loose. In addition, do not solder it.

2) Crimp the blade terminal.

Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve. Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is inappropriate, or t he face is damage d.
